Elastic bed

ABSTRACT

An elastic bed which comprises an elastic bed body having a framework; and a plurality of support springs; wherein each support spring is formed by a steel strip which is firstly circularly arranged along an orientation to a bottom of the framework and then circularly arranged along an opposite orientation to an upper side of the framework; then the process is repeated to a predetermined length; and plurality of positioning elements for positioning the support springs to the framework. The framework is formed by an upper frame and a lower frame; and a plurality of enhancing supports are connected between the upper frame and the lower frame. Each support spring is spaced to another spring with a length greater than a predetermined one so that no support spring is overlapped to another one. A plurality of positioning elements serves for positioning the support springs to the framework.

FIELD OF THE INVENTION

The present invention relates to elastic beds, and particular to an elastic bed having a plurality of support springs; wherein each support spring is formed by a steel strip which is firstly circularly arranged along an orientation to a bottom of the framework and then circularly arranged along an opposite orientation to an upper side of the framework.

BACKGROUND OF THE INVENTION

The prior art elastic bed can be classified into two classes.

In one class, a framework formed by steel strips with larger diameters is used. A plurality of auxiliary frames are installed to the framework. A plurality of support springs are arranged between the plurality of auxiliary frames. The support spring is made of steel strip with a diameter smaller than that of the framework. This kind of elastic bed has advantages of low cost. However, the support springs are overlapped with one another so that the interconnection and interactions of the support springs will make one lying upon the elastic bed feel uneasy.

In another kind of elastic bed, a plurality of independent cylindrical support springs are installed with a framework. The support springs are made of rigid material and enclosed within cotton covers so as to form as independent cylinders. Since the support springs are arranged independently so that the action in one portion of the elastic bed will not affect another portion of the bed. Thereby, it provides a preferred quality to the sleeper. However, this kind of elastic beds is expensive and thus it is not accepted by most users.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide an elastic bed, wherein the elastic bed comprises an elastic bed body having a framework; and a plurality of support springs; wherein each support spring is formed by a steel strip which is firstly circularly arranged along an orientation to a bottom of the framework and then circularly arranged along an opposite orientation to an upper side of the framework; then the process is repeated to a predetermined length. Thereby, it can make the user feel comfortable and is cheap.

Another object of the present invention is to provide an elastic bed, wherein a plurality of enhancing supports are connected between the upper frame and the lower frame so as to prevent the bed to deform due to a great pressure applied thereon.

A further object of the present invention is to provide an elastic bed, wherein each support spring is spaced to another spring with a length greater than a predetermined one so that no support spring is overlapped to another one. Thereby, no noise is generated.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

The elastic bed of the present invention is illustrated with reference to FIG. 1. The elastic bed had the following elements.

An elastic bed body 1 has a framework 10 having an upper frame and a lower frame (in the drawing, a rectangular elastic bed is used as an example, but the present invention is not confined by this example) and a plurality of support springs 20.

The framework 10 is used to support an object placed upon the elastic bed. The framework 10 is formed by rigid steel bodies. The plurality of support springs 20 serves to support the framework 10.

With reference to FIG. 2, it is illustrated that a support spring 20 is formed by a steel strip which is firstly circularly arranged along an orientation to a bottom of the framework 10 and then circularly arranged along an opposite orientation to an upper side of the framework 10. Then the process is repeated to a predetermined length.

Each support spring 20 is spaced to another spring 20 with a length greater than a predetermined one so that no support spring 20 is overlapped to another one. Thereby, when a pressure is applied upon the elastic bed body 1. No noise is generated.

Referring to FIG. 2, at a portion of the support spring 20 which changes the orientation of the support spring 20 has a bending portion 22. In this example, the bending portion 22 has an arc shape, however, other shape of the bending portion 22 is allowable. The installation of the bending portion 22 provides an enhancing support to the elastic bed and serves to save the material of the support spring 20.

Referring to FIG. 2, an auxiliary spring 23 is used to tie upper portions of two support spring portions of a support spring 20, where the two support spring portions have different orientations. The auxiliary spring 23 serves to fix the support spring 20 so as to prevent the relative movement of the different portions of the support spring 20.

A plurality of positioning elements 30 serve to fix the support springs 20 to the framework 10.

Referring to FIG. 3-1, a plurality of enhancing supports 40 are connected between the upper and lower frames of the framework 10. Each enhancing support 40 has an S shape. Each enhancing support 40 has an upper and a lower horizontal ends 41 so that the horizontal ends 41 can be inserted into the positioning elements 30. An arc portion 42 of the enhancing support 40 is at a succeeding section of a respective horizontal end 41 so as to provide a buffer space to the elastic bed. A tilt section 51 is between two arc portions 52 of an enhancing support 40. The orientation of the tilt section 51 is 45 degrees to the respect positioning element 30. A positioning element 30 is used for a respective enhancing support 40 and a respective support spring 20 so as to reduce cost and simplify the assembly process.

With reference to FIGS. 4-1 and 4-2, another embodiment of the enhancing support 50 of the present invention is illustrated. In this embodiment, the enhancing support 50 has the upper and lower horizontal ends 51. Each horizontal end 51 is adjacent to an arc portion 52 of the enhancing support 50 so as to provide a buffer space to the elastic bed. Each arc portion 52 is adjacent to a respective tilt section 51 of the enhancing support 50. Between two tilt sections 51 of an enhancing support 40 has a ring portion 54 for connecting the two tilt sections 51 so as to reduce the deformation of the elastic bed body 1 as a press is applied upon the elastic bed body 1.

The present invention is thus described, it will be obvious that the same may be varied in many ways.
